The Heritage Audio DTT-73 Dual Microphone Preamplifieris a wood and steel chassis dual 80 dB microphone and 10 dB line recording preamplifier module based on the vintage 1073 module designed by Rupert Neve. The remake is intended for recording engineers who want the classic Neve sound in a portable tabletop footprint, but do not need the equalizer functionality of the original 1073. The unit includes a handle for carrying and has the versatility to be used on stage, on the road, in hotel rooms, and other applications outside of a traditional studio.

The preamplifier supports selectable HI-LO minimum balanced and floating input impedances that accommodate a range of microphone types including vintage ribbons. A +24/48V phantom power button with separate phantom voltage indicator lights is included on both channels, as well as an input level knob for adjusting to your source. You can also switch the module into line mode to re-amplify pre-recorded tracks and add color to a mix.

Plugging in a mono 1/4" input into the DI port on the front of the unit automatically switches the module from MIC to DI mode. On each channel, the unit also includes a 1/4" DI thru jack for connecting to an instrument amplifier when using the unit live on stage. A selectable discrete component Class A 3rd-order 80 Hz high-pass filter with an 18 dB per octave slope has been added for recording sources without the effects of low-frequency coloration. An output control knob is included to prevent overloading the preamplifier.

The unit is powered by an internal noiseless worldwide power supply designed to reduce the effects of electromagnetic interference on the audio transformers. A ground lift switch is included to remove ground loops. The preamp features gold-plated Neutrik XLR input and output connectors. To achieve the classic feel of the original 1073, the unit is constructed with Marconi-style knobs and vintage engraved pushbuttons for the DI, low impedance, line, pad, phase, and high-pass functions.

Q: 1. Hi , can use and record for instruments too?

A: Yes you can. It functions as a mic pre and a direct box. So you can use it on a mic or an instrument.

Q: 2. how do you connect to speakers that only have xlr inputs?

A: A cable such as the Pearstone PM Series 1/4" TRS Male to XLR Male Professional Interconnect Cable (6'), BH #PEPMTRSXM06 will allow you to connect to the balanced 1/4-inch output of the audio interface into the balanced XR input of a studio monitor.

Q: 3. I want to use it in Korea. 110v? 220v? Please check the voltage.

A: At this time, we can only confirm the unit as a 120v device. For use in Korea, would we recommend the use of a set down voltage transformer.

Q: 4. Should I go with this or the Studio Projects B1 for general studio use? I know I just asked a similar question a few days ago but I've narrowed it down to these 2 and need help choosing.

A: Without knowing anythigng about your projects and your needs I would lean to the MXl as an all purpose mic.

Q: 5. Hi, will this work on an AMD Ryzen system?

A: It would depend on the computer's operating system. It may be best to contact Universal Audio with the details about the system you have to check on compatibility. You can reach their customer support agents by phone at 877-698-2834 or 831-440-2436 from 9 AM to 1 PM Pacific Time on Mondays, Tuesdays, Thursdays, and Fridays (phone support is not available on Wednesdays).

Q: 6. Can you connect from spdif to optical?

A: To connect a SPDIF output signal to the optical input of the Universal Audio Apollo Twin X DUO Heritage Edition Desktop 10x6 Thunderbolt 3 Audio Interface with Real-Time UAD Processing you will want to use a converter to change the coax SPIDF connection to a Toslink Optical connection.

Q: 7. Hello, Can this unit be used together with X-Air12? Thanks.

A: Yes, it can.

Q: 8. Can this be battery powered? I'm looking for a small preamp to put on my camera.

A: It works off of a 9V 1000mA AC wall-wart . Theoretically, if you have a battery that can output that amount, it should run. However, do note that tube preamps (otherwise known as Class A preamps ) are power-hungry, inefficient, require several minutes of warm-up before accurate use, and heat-intensive, but provide the best signal-to-noise ratio when adding amplifying a signal (thus they are a staple for using very low-signal mics such as ribbon mics). However, for a portable solution to strap to a camera, this is far from ideal due to heat, power consumption/efficiency, and the fact that it is not designed to be mounted on a camera but rather set on a table- it's best (and designed) use is recording music or VO work in an indoor scenario.
